Eat Anything Rx Review (2026): Does Xylose Isomerase Really Stop FODMAP Bloating?

If certain foods — an apple, a bowl of beans, a slice of onion-topped pizza — reliably leave you bloated and gassy a couple of hours later, the culprit is often FODMAPs: a group of fermentable carbohydrates that some guts struggle to absorb. Eat Anything Rx is a digestive-enzyme capsule from Dirobi built specifically for that problem. The short version of this review: it is one of the few over-the-counter blends that targets fructose alongside the usual carbohydrate, protein, and fat enzymes, so if your bloating is FODMAP-driven it is a sensible, low-commitment thing to try. It is not a cure, and it will not fix the underlying intolerance — it is a tool you take with a meal to ease symptoms.

What Eat Anything Rx actually is

Eat Anything Rx is a vegan, non-GMO digestive-enzyme capsule, made in the USA in a GMP facility. You take one to two capsules zero to twenty minutes before a meal, and the enzymes work in your gut to help break down the components of that meal that commonly cause trouble. It is positioned not as a daily supplement you take forever, but as something you reach for before the meals you know tend to bother you — the high-FODMAP ones.

What sets it apart from a generic enzyme product is the combination it puts in a single capsule. Most enzyme blends cover carbohydrates, protein, and fat. Eat Anything Rx adds two enzymes aimed squarely at the FODMAP problem: xylose isomerase for fructose, and alpha-galactosidase for the carbohydrates in legumes and beans.

How the enzymes work

The headline ingredient is xylose isomerase, dosed at 30 mg per capsule. Fructose malabsorption — where the small intestine struggles to absorb fructose — is a common driver of bloating and gas after fruit, honey, and many processed foods. Xylose isomerase helps convert fructose into glucose, which the body absorbs more easily; the manufacturer states each capsule can help process roughly 20 grams of fructose. Research suggests this enzyme may reduce the symptoms people with fructose malabsorption experience, though it works on the sugar, not on the underlying condition.

Around that sits the APLC enzyme blend, which covers the major food groups: amylase for carbohydrates, protease for protein, lipase for fats, and cellulase for fiber. Alpha-galactosidase — the same class of enzyme found in popular anti-gas products — targets the hard-to-digest carbohydrates in beans, legumes, and certain vegetables. Finally, the formula includes Lacto-Wise, a shelf-stable probiotic paired with a prebiotic, intended to support the gut more broadly rather than to act on any single meal.

Taken together, the logic is straightforward: give the gut extra enzymatic help with the specific components of a meal that tend to ferment and produce gas, and you may feel less bloated afterward. The Monash University FODMAP program — the team that defined the low-FODMAP approach — describes why these carbohydrates cause symptoms in sensitive people, and enzyme support is one of several strategies that may help.

Who it's for

Eat Anything Rx makes the most sense for a specific person: someone whose bloating, gas, and discomfort track clearly with high-FODMAP foods. That includes people with diagnosed or suspected fructose malabsorption, people who react to beans and legumes, and people with IBS-type bloating who have noticed that fermentable carbohydrates are a trigger. If you have done a low-FODMAP elimination and want a way to occasionally eat the foods you have cut out — the apple, the hummus, the garlicky restaurant dish — this is the category of product designed for exactly that moment.

It is far less useful if your digestive issues are not FODMAP-related. Enzymes that target fructose and legume carbohydrates will not do much for reflux, lactose intolerance specifically (the blend is not a dedicated lactase product), or discomfort with no clear food pattern.

How to use it

Take one to two capsules zero to twenty minutes before the meal you expect to be a problem. Because it works on the food in that meal, timing matters — it is a before-you-eat product, not an after-the-fact remedy. Many people start with a single capsule and move to two for larger or higher-FODMAP meals. As with any supplement, if you are pregnant, managing a health condition, or taking medication, check with a qualified healthcare professional first, and treat persistent digestive symptoms as a reason to see a clinician rather than to self-treat indefinitely.

Honest pros and cons

What we like

• Targets fructose with xylose isomerase — a FODMAP-specific enzyme that is rare in over-the-counter blends.
• Broad-spectrum: the APLC blend plus alpha-galactosidase covers carbs, protein, fat, fiber, and legumes in one capsule.
• Vegan, non-GMO, and made in the USA in a GMP facility.
• Flexible, situational dosing — you take it only before the meals that tend to bother you.

What gives us pause

• No money-back guarantee is stated, so there is more risk if it does not work for you.
• Premium price relative to single-enzyme products, starting at $29.95 for a 30-count bottle.
• Enzymes ease symptoms; they do not address the root cause of a FODMAP intolerance.

Who should skip it

If your symptoms are not clearly tied to high-FODMAP foods, this is probably not your product — the very things that make it distinctive (fructose and legume enzymes) are wasted on problems they were not designed for. People looking specifically for lactose support, reflux relief, or a daily probiotic as their main goal will be better served by something purpose-built. And anyone wanting an ironclad refund safety net should note there is no stated money-back guarantee.

The verdict

Eat Anything Rx is a thoughtfully built, FODMAP-aware enzyme blend that does something most competitors do not: it tackles fructose head-on with xylose isomerase while still covering the everyday food groups. For someone whose bloating is genuinely FODMAP-driven, it is a reasonable, low-commitment tool to keep on hand for the meals you would otherwise avoid. The honest caveats are the premium price, the absence of a stated money-back guarantee, and the reality that enzymes manage symptoms rather than resolve the underlying intolerance. If you want to test the waters before committing to a full bottle, Dirobi's free-trial offer is a lower-risk way to see whether it works for your gut.
